fast commit :
make native mips loading an option to prevent performance lost in game that not need this functionality.( thanks to dorian.fevrier for point the performance lost.) added a patch from pierre@pirsoft.de to avoid vertex drops when index array is full in opengl implementation that do not support large index arrays git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5432 8ced0084-cf51-0410-be5f-012b33b47a6e
